GENERAL: The National Park Service (NPS), Department of Interior, anticipates issuing a solicitation for the project described below. This is a pre-solicitation notice only and does not constitute a solicitation; accordingly, no response is due at this time. Specific instructions on submitting proposals will be contained in the solicitation documents. It is anticipated that the solicitation will be issued on or around -2/1/2024. The entire solicitation package, including all attachments, will be available electronically at www.sam.gov Paper copies of this solicitation will not be made available. PROJECT SCOPE: The National Park Service (NPS) Cape Hatteras National Seashore (CAHA) has a requirement to replace the septic tank and drainfield at the Volunteer in the Park (VIP) Recreational Vehicle (RV) Pads on Fort Raleigh National Historic Site (FORA). A large concrete area located adjacent to the A-frame house at 1415 Pear Pad Rd is utilized for two RV / trailer parking pads to house NPS employees or volunteers for extended periods. The concrete pads provide Electrical, Potable Water, and Septic connection points adjacent to the pads. The septic pipes run under the concrete and immediately adjacent to the concrete park area emptying into a septic tank. The septic tank is located between the concrete pad and the driveway for the A-frame house. The septic tank effluent flows by gravity to a drainfield. The drainfield consists of several lines of perforated PVC pipe. The drainfield lines run partially beneath a sidewalk and accessible ramp leading to the A-frame entrance. The existing tank is approximately 750 gal and drainfield measures approximately 15 ft wide and 40 ft long. The system is past its useful life, does not properly drain, and has been encroached by a nearby tree and other vegetation roots. Sewage is being pumped periodically from the septic tank to allow limited usage of the VIP Pads. The site was examined according to North Carolina Administrative Code Title 15A Chapter 18 Environmental Health Subchapter 18A Sanitation Section .1900 Sewage Treatment and Disposal Systems and the October 20, 2017 Memorandum regarding Permitting and Design Guidance for Wastewater Treatment and Dispersal Systems for Recreational Vehicle Parks ¿ Revised. Specifically, the topography, landscape, soil wetness condition and water table depth, soil depth and restrictive horizons, daily flow rate, and setbacks for the location of tank and drainfield. Consultation with the Dare County Public Health On Site Water Protection Branch provided helpful information on the soil type in the Housing area as a Sandy Loam. A percolation test was not conducted on site due to the sandy nature of the soil. A maximum Long Term Acceptance Rate of 0.8 is allowable for the drainfield sizing calculations, depending on the type of drainfield installed. Replace the septic system with a new septic system meeting North Carolina Building Code: Plumbing Code, North Carolina Administrative Code 15A NCAC 18A, and supplemental memorandum dated October 20, 2017 regarding Permitting and Design Guidance for Wastewater Treatment and Dispersal Systems for Recreational Vehicle Parks ¿ Revised. New septic system shall be installed by a qualified installer according to North Carolina General Statues. Installers with qualifications from another state are acceptable. 1. Empty existing septic tank from solids and fluids. 2. Demo existing 750 gal concrete septic tank and distribution tank. a. Do not remove or damage or undermine existing concrete RV parking pads, the existing accessible ramp, or the adjacent house. Protect trees not designated for demolition from damage due to heavy equipment or other work. 3. Demo existing drainfield components: a. Remove existing pipe from VIP Site 2 to the existing septic tank. b. Disconnect the existing drain pipe from VIP Site 1 at the Wye connection with Site 2. Ensure the disconnection is approximately 6 inches away from the edge of the existing concrete RV parking. c. Demo the existing drainfield pipes and associated gravel / drainfield material. Do not damage the existing accessible boardwalk into the adjacent housing unit. 4. Completely remove trees designated on the attached drawings, a total of up to 5 full sized trees and 5 smaller trees (less than 8 inches in diameter at breast height) - trees which roots extend into new drainfield location. Completely remove stumps and roots up to 4 ft deep within the drainfield location and a 15 ft shoulder area around the drainfield. Only remove trees which are designated to be removed. Trees not identified in this scope of work, but which must have roots removed in order to install the new septic system shall be identified to the COR prior to removing roots. Roots from other trees which extend into the proposed location of the new septic tank, distribution box, and drainfield trenches shall be removed to 15 ft away from the new trench. 5.

Dispose of roots off site. Reuse existing sandy loam soil for drainfield fill which is free of roots, leaves, and other organic material so that soil is chroma 3 or less according to the Munsell Color Charts. Reused soil shall be ¿Suitable¿ as defined by 15A NCAC 18A paragraphs .1939 - .1948 with special attention to paragraph .1941 SOIL CHARACTERISTICS. 15A NCAC 18A is attached to this scope of work for reference. 6.
